Key legal question
Whether the appellant proved performance or offer of performance under Art. 82 CO despite the respondent's objection of non-performance.
Extracted holding
The appellant did not prove that he had fully performed or offered to perform his contractual obligations; the exception of non-performance was therefore available to the respondent.
Extracted reasoning
The lower courts' factual findings that the transferred assets were incomplete and that the appellant had not shown all promised efforts to facilitate the transfer of clientele were upheld; the appellant's criticism was merely appellatory and therefore inadmissible.
